UNITED STATES PATENT OFFIoE PARDON BOYDEN, OF AMSTERDAM, NEW YORK,ASSIGNOR OF ONE-HALF HIS RIGHT TO OSCAR F. NELSON, OF SAME PLACE.

IM PROVEME'NT IN STOVE-G RATES.

Specification forming part of Letters Patent No. 115,021, dated May 23,1871.

To all whom it may concern:

Be it known that I, PARDON BOYDEN, of Amsterdam, in the county ofMontgomery and in the State of N ewYork, have invented certain new anduseful Improvements in Grates, Dumping and Shaking Apparatus toGoal-Stoves; and do declare that the following is a full, clear, andexact description thereof, reference being had to the accompanyingdrawing and to the letters of reference marked thereon making a part ofthis specification.

The nature of my invention consists in the construction and arrangementof a grate for coal-stoves, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1 is a plan view; Fig. 2, a front elevation; and Fig. 3, avertical section of my grate. Fig. 4 represents a cross-section of thegrate-box, frame, and double grates. showing one grate thrown upward.

A A represent two semicircular wrought or cast metal bar-grates ofsufficient size, so that when placed together the two will form acircular grate of any required size. At each end of the inner bar ofeach semicircular grate is made a knee-shaped bearing, B, rising upwardand outward above the upper face of the grate in position, which formwill place the grate, when in position, as hereinafter described, belowthe bearings. (J represents a circular wrought or cast metal frame orrim, with grooves or slots in the upper edge on opposite sides, whichare intended as mortise bearings or receptacles for holding andsustaining the knee-shaped grate-bearings B B. This circular frame orrim is placed within the stove, and rests upon flanges or pins a a, ormoves on rollers protruding inward beneath it from the inner sides ofthe stove or fire-box D. The knee-shaped bearings on that end of eachsemicircular bar-grate which is intended for the front of the stove aremade of sufficient length to allow the ends of such hearings to passthrough a slot or aperture in the front side of the stove, and areconstructed in such a shape that when the grate is placed in positionwithin the stove the ends of these will be turned one to the right andthe other to the left hand on the outside of the stove, which bearingends B B so placed are intended as levers with which to dump the grate.The dumping is produced by turning these levers B B or bearing ends inan upward direction toward each other. In the front side of the stove,and beneath the levers B, is made an elongated slot or mortise throughthe stove for the purpose of receiving a shaking-iron, E, which passesthrough this elongated slot or mortise into the side of the circularframe or ring 0 containing the grate.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. A centrally-bisected grate, hung below its journaled bearings, asdescribed, so that both sections of the grate can be dumped withoutremoving the bearings, upon which it is lifted, from their positions,substantially as herein set forth.

2. The combination of the semicircular bargrates A A, knee-shapedbearings B B, levers B B, and circular frame or rim 0, all constructedand arranged to operate substantially as and for the purposes herein setforth.

In testimony that I claim the foregoing I have hereunto set my hand this27th day of February, 1871.

PARDON BOYDEN. Witnesses:
